Correct me if I'm wrong but not all browses seem to send a undefined value for blank form fields, some tend to send '' (aka, nothing [blank string]).
PHP Code:
function is_empty($value){
if ($value === '' || empty($value)){
return false;
}
return true;
}
if (is_empty($firstname) || is_empty($lastname) || is_empty($emailaddress)) {
$message = "Please fill in all fields!";
} else {
